British pop star Lily Allen has suffered a miscarriage.The Smile singer, who was around six months pregnant by her boyfriend Sam Cooper, was admitted to hospital on Thursday morning (28Oct10) after complaining of stomach pains. The 25-year-old spent the weekend (29-30Oct10) being treated by doctors, but efforts to save her baby tragically failed, according to British newspaper The Sun. A statement from the star's representative confirms the news: "It is with great sadness that we have to confirm that Lily Allen and Sam Cooper have lost their baby. "The couple ask that their privacy be respected and that they be left alone at this deeply distressing time. No further comment will be made." Allen previously suffered a miscarriage in 2008 just months after she announced she was expecting a baby with Chemical Brothers star Ed Simmons. She has been dating decorator Cooper since July 2009.
